Note: Value should be greater than 0.

Formulas to find Stiffness of Valve Spring

Lift of Valve

Lift of Valve is the height to which the valve is lifted during operation for the flow of gases.

Symbol: h_max

Measurement: LengthUnit: mm

Note: Value should be greater than 0.

Formulas to find Lift of Valve

Other formulas in Valve Lift category

Go Maximum Lift of Valve given Diameter of Port and Valve Seat Angle

h max = \frac{d p}{4 \cdot \cos (α)}

Go Diameter of Port given Maximum Lift of Valve

d p = 4 \cdot h max \cdot \cos (α)

Go Valve Seat Angle given Maximum Lift of Valve

α = \arccos (\frac{d p}{4 \cdot h max})

Go Maximum Lift of Valve for Flat Headed Valves

h max = \frac{d p}{4}

How to Evaluate Force Required to Lift Engine Valve?

Force Required to Lift Engine Valve evaluator uses Force to Lift Engine Valve = Stiffness of Valve Spring*Lift of Valve to evaluate the Force to Lift Engine Valve, The Force required to lift engine valve is the amount of extra spring force over the initial spring force that is required to lift the valve. Force to Lift Engine Valve is denoted by P₂ symbol.
